Control of Wheat Pests and Weeds
Main Harmful Weeds
- Wild oat species (Avena sterilis L., A. fatua L.) Poaceae
- Foxtail (Alopecurus myosuroides Huds.) Poaceae
- Canary grass species (Phalaris spp.) Poaceae
- Wild mustard (Sinapis arvensis L.) Brassicaceae
- Hedge mustard (Boreava orientalis Jaub. et Spach.) Brassicaceae
- Scented root (Bifora radians Bieb.) Apiaceae
- Spreading knapweed (Centaurea depressa Bieb.) Asteraceae
- Bedstraw (Galium spp.) Rubiaceae
Chemical application is made during the wheat tillering stage and when weeds are in the 4-6 leaf growth stage.
The activation of the chemicals used in the application should occur at 10°C or higher. The application should be postponed until the required temperature is reached.
The application program should be planned for sunny weather with rain expected the following day.
Applications should be made in windless conditions.
Care should be taken regarding neighboring fields with cultivated crops, and applications should be made at low altitudes using UAVs.
Herbicide chemicals can be contact, systemic, or translaminar in action.
No other pesticides should be mixed with the weed control chemicals.
For mixtures, 1 liter per decare can be used.
Depending on the chemical used, the dosage can be reduced by 20%.
Appropriate calibration and parameters based on the pesticides used:
baibars CT33s
- Height (altitude): 2.0-2.5 meters
- Working width: 6.0 meters
- UAV speed: Average 4.0-5.0 m/s
baibars CT50s
- Height (altitude): 3.5-4.0 meters
- Working width: 7.0 meters
- UAV speed: Average 4.0-5.0 m/s
Wheat Rust Diseases
- Yellow rust (Puccinia striiformis West) (= P. striiformis var. striiformis)
- Brown rust (P. recondita f.sp. tritici Rob. et Desm.)
- Black rust (P. graminis f.sp. tritici Eriks. et Henn.)
Chemical Control
The application should be made during the yellow rust period. If not applied on time, it may cause a 60% yield loss.
The early-stage symptoms of yellow rust on the lower leaves can be observed every year. Therefore, the progression of the disease should be monitored, considering climate conditions (%90 relative humidity and temperatures of 15-20°C). When the disease progresses towards the upper parts of the plant, the upper leaves, especially the flag leaf, should be sprayed to prevent the spread of the disease. If the climatic conditions are favorable for disease development and there is a potential for an epidemic, the application can be repeated based on the duration of the pesticide's effectiveness. Pesticide application should not be performed one month before harvest, as the plant enters the maturation stage.
The required amount of liquid for the activation of the fungicides used should be applied. Generally, 2.5 liters of mixed liquid per decare should be applied. This amount may vary depending on the chemical pesticide used.
Appropriate Calibration and Parameters Based on the Pesticides Used:
baibars CT33s
- Height (altitude): 2.5 - 3.0 meters
- Working width: 6.5 - 7.0 meters
- UAV speed: Average 6 m/s
baibars CT50s
- Height (altitude): 3.5 - 4.0 meters
- Working width: 7.5 - 8.0 meters
- UAV speed: Average 6 m/s
